Introduced into a natural environment, a robot tracks the sun in order to ensure its own survival. Autonomous in energy and in its movements, the robot simulates the basic behaviour common to all living creatures: the survival instinct. An entity that is neither alive nor inert, the robot was designed exclusively to survive in a specific environment. The film, which is neither a fiction nor a documentary, presents the portrait of this object in time. To obtain its goal, the robot must adapt to its environment, to the irregularities of the ground, to the presence of obstacles or animals. Since its behaviour is unpredictable, the writing of the film consists in adapting to the robot’s actions. There are no events, no script. In the film it is not so much the robot that must adapt to the environment as the environment that adapts to the robot’s presence as it tries to find a place for itself, to insert itself into a score where vegetable, mineral and animal have already entered a dialogue.
